Did you know?

Cement is responsible for 85% of concrete’s CO2 emissions, even though it represents only 12% of its composition.

Clinker, its main constituent, produced by firing limestone and clay, is responsible for cement’s carbon footprint due to:

  • Heating cement kilns to 1500° (1/3)
  • The chemical reaction that releases carbon during baking (2/3)
  • Industrial by-products: blast furnace slag, fly ash, etc.
  • Natural materials: pozzolan, calcined clay, limestone filler
